TARGET YIELD GUIDE

Bluetooth scale target-yield and auto-stop workflow for Micra

IRIS4 target-yield behavior depends on the remote, dosing chip, scale pairing, cup placement, firmware version, and a stable shot workflow. This guide sets expectations before ordering or support.

How does target-yield auto-stop work?

Target-yield auto-stop pairs a compatible Bluetooth scale with the IRIS4 remote and dosing chip. The system watches the live weight reading and uses the configured target as the stop condition, so stable scale placement and firmware matching matter.

What affects reliability?

Bluetooth signal quality, scale sleep behavior, cup movement, drip-tray fit, firmware version, and installation quality all affect results. If behavior changes after an update, check the OTA firmware guide and retest with a simple workflow.

When should support be contacted?

Contact support when the scale cannot pair, readings freeze, stop timing is inconsistent, or the shot workflow differs from the guide after firmware and installation checks. Include order number, scale model, firmware version, and a short video.

Does target-yield auto-stop need a Bluetooth scale?

Yes. The workflow depends on a compatible Bluetooth scale sending stable live weight readings.

Why can auto-stop be inconsistent?

Scale sleep, Bluetooth signal, cup movement, firmware version, and installation quality can all affect stop timing.

What information helps support?

Provide the order number, scale model, firmware version, issue symptoms, and a short video.

ORDER FLOW

Target-Yield Check Path

  1. Install and verify the dosing PCBA first.
  2. Pair the compatible Bluetooth scale and confirm live readings.
  3. Set a target yield and test with water or a controlled espresso workflow.
  4. If the stop point is unstable, check scale placement, firmware, and support notes before changing hardware.

NOTES

Workflow Notes

  • Auto-stop depends on measurement stability; it is not a substitute for safe operator attention.
  • Scale compatibility and firmware behavior can change by batch.
